My Whirlpool gas (LP) dryer Model LGR6634BN0 suddenly stopped heating. I checked to see if the igniter was glowing. It was not. I replaced it. Still no heat. I then replaced the solonoid coils, the flame sensor. Still no heat. Next I replaced the thermal fuse and cycling thermostat. At first no heat. After a few minutes the dryer started producing the high heat it should and the igniter was glowing. Then the dryer cut down to very low heat outout and has stayed that way. The igniter continues to glow as it should. The only other part I can easily replace is the hi-limit thermostat. I don't know if replacing the hi-limit thermostat could be the missing piece of this puzzle. Does anyone have any ideas of what the problem could be? By the way, the exhaust vent is brand new and clear

It is not likely the hi limit thermostat. The high limit thermostat cut the heat of if the dryer over heats.

It may be the cycle selector switch.
